Comment (by ncohen):
> We discussed this at the Sage Days last week (unfortunately you were not
there).
I'm pretty sure that I was, but I admittedly have a very poor memory.
> The best way might be to have an option in Posets which would allow to
create posets with and without an attached linear extension.
And that would be the default Poset.
> Your use case would be in the new default case of no linear extension
attached.
My use case is the definition of what a Poset is. In any book. Also, do we
overlook the fact that this is a conceptual problem of categories, and
equalities, an parents, and all that stuff ?
